Hi @satoru,

The community has rallied behind the ElixirLS extension, which is the most actively maintained. Perhaps see if it serves your purpose?

I wouldn’t expect vscode-elixir to work properly on anything newer than elixir 1.5. it uses an over 3 years old elixir_sense dependancy. A lot has changed in elixir internals since then (especially in 1.7 and 1.10).

@satoru Could you post a more complete error log from ElixirLS?. Also how did you install erlang and elixir?
Please note that for ElixirLS to work other extensions may need to be disabled.

Thanks. It looks like your project dir is set to nil for some reason.
It’s crashing in line

Path.join([project_dir, ".elixir_ls", ".gitignore"])

Try setting it to . in extension settings
